J. W.' WARREN cogvcn'rs TIL:

Sept 7,1926.

Original Filed June 11'. 1923 /ll [lill/M and prevent leakage. -ticularp adapted to.l extend iinder the semi-cylindrical portion 2 of an adjacent tile and the ribs 11 and 12 on the under side of pirtion 2 willfcgut oca 'llar attra ion .an l. p event sind thglikyfrom orking nuclei' the edge 1 of one tile and passing up the portion 4 whichlies beneath the saine. The tile is providedV with twovdownwardg extending transverse end ribs 6 and 7 whl as shown in Fig. 1, are designed to engage eleataand 9 arranged'on the roof 10,1n order to prevent longitudinal vmovement 0f the tiles.

111,1' additiontothe endf ribs 6 and 7, the tileA is also provided with de endingatransverse ribs 11 and 12'which nction to reinforce the tile, and act as cleat engaging members when'the'tile is Ydividied transversely. 4 Rin-instance if a oint Iin the .roof is reached where a tile o full length cannot be used, then the tile -is divided so that the part used is either-one-third or two-thirds the entire length of the original tile. -Un der such circumstances either the rib 11v or 12 may engage the cleat 9 on the roof; Rib 6 also serves to cut olf ca illaryattraction An it-will be arnoted that the ribs', 7,"11 an 12 aforesaid, together with the body of the tile, are of equal depth'or thickness at al1 points lwhenmeasured in perpendicular planesfromthe base line of said ribs.

The intermediate portion 3y ofthe tile is provided on its under side with de ressions 13 which Vdo not' extend entirely through the tile. These depressions are-pro vided to enable a Vnail to be driven through the tile at a desired point without splitting the tile. A number of these depressions 13 are laced in each tile, so that a nail may be 'ven through one ofthe depressions 'even thoughfthe tile has been' cut transverselxyuor diagonally into a piece`one-third or-,two-thirds ory any size 'of its original length. For instance, if the end portion of y the tile beyoiidthe rib 12 is cut oil', then 13 lying between the one of the depressions ribs1'11and 12 Vmay be utilized in'driving the nail.

Diagonall 'opposite corners 'of thel tile are provide with parallel edges 14 and 15 to facilitate laying the tiles. As shown i-n Fig. 2,2 the edge 15 of one tile abuts a ainst theedge 14 of an adjacent tile in a ower row and this' engagement aids in shifting-movement of either tile.

From the foregoing it is believed that the lconstruction fof the tiles andthe manner of laying thesame will be readily understood, and it is apparent that changes in dwg Amay beirresorted to within the scope of y ap nded claims. n What' claim and desire to Letters Patent is:

secure by 1. A roofing tile of pantile form includpreventing ing transverse downwardly-extending cleatengaging ribs, which latter together with the body of the tile are of equal thickness at all points when measured im rpendicular planes from the Base line left ribs aforesaid.- e

2.y A roofngtileof pantile `form including transverse downwardly-extending cleatengaging end ribs, which latter together with the body of the tile are of equal thickness at all points whenmeasured inrperpendiciilar planes l,from theba'se line of t e ribs aforesaid.

3. A'roongtile, of; pantile form having l parallel sides'and transverse downwardlyextending cleat-engaging ribs, whiclnlatter together withthe body of the tile are of equal thickness at all points when measured in'perpendicular-.planes from the base line of the ribs aforesaid. .i

4.. A tile including Vtransverse down-, wardl -extendin cleat-engaging end ribs, space downwar termediate ribs and nail receiving cavities formed in said tile throughout its length, 'all constructed and arranged to provide 'cleate engaging ribs and means for fastening the tile. to the roof when said tile is transversely dlVded. "f

5. A tile including a substantially semicylindrical portionV terminating in a horizontal edge, an^ intermediate portion merging into the substantially semi-cylindrical portion and having an unobstructedupper surface in substantially the samev plane'as said horizontal edge, an upwardly and outwardly inclined portion merging into said intermediate .portion and forming an Ved y extendingtransvense in- -f portion of the tile adapted to rest beneatlrt e substantially lsemi-cylindrical rtion of a similar tile, transverse end ri projecting downwardly from the under surfaceof the tile,.and continuous transverse downwardly 6. A cement or concrete tile including transverse downwardly-extending 'cleat-engagi-ng end ribs, which latter together with the body of the tile are of equal thickness at all points when measured in perpendicular planes from the base line of the ribs aforesaid, in combination with spaced downwardly-extending transverse intermediate ribs, said intermediate ribs constructed yand arran" Ato form cleat-engaging ribs when the t' e is divided transversely.
